Comparing Three Depreciation Methods Dexter Industries purchased packaging equipment on January 8 for $300,000. The equipment was expected to have a useful life of four years, or 6,400 operating hours, and a residual value of $24,800. The equipment was used for 2,240 hours during Year 1, 1,344 hours in Year 2, 1,792 hours in Year 3, and 1,024 hours in Year 4. Required: 1. Determine the amount of depreciation expense for the four years ending December 31 by (a) the straight-line method, (b) the units-of-activity method, and (c) the double-declining-balance method. Also determine the total depreciation expense for the four years by each method. Round the answer for each year to the nearest whole dollar. Depreciation Expense Units-of-Activity Straight-Line Method Method Year Double-Declining- Balance Method Year 1 Year 2 $ Year 3 $ Year 4 $ $ Total 2. What method yields the highest depreciation expense for Year 1? 3. What method yields the most depreciation over the four-year life of the equipment? A building with a cost of $600,000 has an estimated residual value of $240,000, has an estimated useful life of 18 years, and is depreciated by the straight-line method. a. What is the amount of the annual depreciation? Do not round intermediate calculations. $ b. What is the book value at the end of the tenth year of use? C. If at the start of the eleventh year it is estimated that the remaining life is 10 years and that the residual value is $170,000, what is the depreciation expense for eac of the remaining 10 years? $
